vi PREFACE. 
To W.S. M. D’'Ursay, Esq., for a collection of plants from 
British Caffraria, containing several rare species. 
To Miss Extiott, daughter of the late Rev. W. ELLiort, 
of the Paarl, an early collector of Cape plants, for a most 
interesting parcel of the plants of Damaraland, a region as 
yet but very imperfectly explored, not ordinarily accessible to 
botanists, but known to possess a highly curious Flora. From 
this region has recently been sent to Kew, a singular plant, the 
“Tumboa” of the natives, (Welwitschia mirabilis, Hook. f., 
—a stemless conifer !*) of which we are most anxious to receive 
specimens of various ages. 
To the Rev. Henry WHITEHEAD, for a collection of plants 
from Namaqualand, carefully dried and well selected, containing 
some new and many rare species, in better condition than any 
which we have previously received from that arid district. 
To our friends Dr. ATHERSTONE and Henry Hutton, Esq., 
we are more especially indebted for their voluntary and zealous 
exertions in making known throughout the frontier districts, 
both the “Fora” and the “THESAURUS,” and kindly acting 
as our agents in distributing both works, Nor can we close 
this imperfect expression of thanks to our many kind friends, 
without again recording the obligations we are under to the 
Hon. Rawson W. Rawson, Secretary to Government, for his 
' continued care in transmitting parcels of plants sent to his 
office by our various correspondents. Without this aid, and 
the privilege of post-transit for small parcels afforded to us by 
the Colonial Government, we should suffer under many delays 
and expenses which are now saved to us.
